usayizi omncane, uphephile futhi akukho ukunakekelwa.
LiFePO4 Ukuphepha kwebhethri
Amabhethri Asekelwe ku-Lithium ngokushesha aba ukumiselela okunengqondo kobuchwepheshe beminyaka engu-150 ubudala bamabhethri e-Lead-Acid.
Ngenxa yokungaqini okungokwemvelo kwe-lithium metal, ucwaningo lushintshele ebhethrini le-lithium elingelona elensimbi lisebenzisa i-lithium ion. Nakuba iphansi kancane ekuminyana kwamandla, isistimu ye-lithium-ion iphephile, ihlinzeka ngezinyathelo ezithile zokuphepha ezihlangatshezwana nazo lapho ishaja futhi ikhishwa. Namuhla, i-lithium-ion ingenye yamakhemikhali ebhethri aphumelela kakhulu futhi aphephile atholakalayo. Amaseli ayizigidi eziyizinkulungwane ezimbili akhiqizwa minyaka yonke.
I-LiFePO4 (eyaziwa nangokuthi i-Lithium Iron Phosphate) amabhethri ayintuthuko enkulu kune-asidi yomthofu ngesisindo, umthamo kanye nempilo yeshelufu. Amabhethri e-LiFePO4 awuhlobo oluphephe kakhulu lwamabhethri e-Lithium njengoba engeke ashise ngokweqile, futhi noma ebhobokile ngeke avuthe. Izinto ze-cathode kumabhethri e-LiFePO4 aziyona ingozi, ngakho-ke azibeki izingozi zempilo ezimbi noma izingozi zemvelo. Ngenxa yokuthi umoya-mpilo uboshelwe ngokuqinile ku-molecule, ayikho ingozi yokuthi ibhethri liqhume livutha amalangabi njengoba kwenzeka nge-Lithium-Ion. Ikhemistri izinzile kangangokuthi amabhethri e-LiFePO4 azokwamukela ukushajwa okuvela kushaja yebhethri emiswe i-lead-acid. Nakuba amandla amancane kune-Lithium-Ion ne-Lithium Polymer, i-Iron ne-Phosphate miningi futhi ishibhile ukuyikhipha ngakho izindleko zinengqondo kakhulu. Iminyaka yokuphila ye-LiFePO4 cishe iminyaka eyi-8-10.
Kuzinhlelo zokusebenza lapho isisindo sicatshangelwa, amabhethri e-Lithium aphakathi kwezinketho ezilula kakhulu ezitholakalayo. Eminyakeni yamuva nje i-Lithium isiyatholakala emakhemikhali amaningana; I-Lithium-Ion, i-Lithium Iron Phosphate, i-Lithium Polymer nezinye izinhlobonhlobo ezimbalwa ezingavamile.
Amabhethri e-Lithium-Ion namabhethri e-Lithium Polymer angamandla aminyene kakhulu kumabhethri e-Lithium, kodwa ayashoda ekuphepheni. Uhlobo oluvame kakhulu lwe-Lithium-Ion yi-LiCoO2, noma i-Lithium Cobalt Oxide. Kule chemistry, i-oxygen ayiboshiwe ngokuqinile ku-cobalt, ngakho-ke lapho ibhethri lishisa, njengokushaja okusheshayo noma ukushajwa, noma ukusebenzisa nje kanzima, ibhethri lingakwazi ukubamba umlilo. Lokhu kungaba yinhlekelele ikakhulukazi ezindaweni ezinengcindezi ephezulu njengezindiza, noma ezintweni ezinkulu ezifana nezimoto zikagesi. Ukusiza ukulwa nale nkinga, amadivayisi asebenzisa amabhethri e-Lithium-Ion ne-Lithium Polymer kudingeka abe nezinto zikagesi ezizwela kakhulu futhi ngokuvamile ezibizayo ukuze ziwaqaphe. Nakuba amabhethri e-Lithium Ion ane-intrinsically high energy density, ngemva konyaka owodwa wokusebenzisa amandla e-Lithium Ion azobe ehle kakhulu kangangokuthi i-LiFePO4 izoba namandla afanayo, futhi ngemva kweminyaka emibili i-LiFePO4 izoba namandla amakhulu kakhulu. Okunye okungalungile kwalezi zinhlobo ukuthi i-Cobalt ingaba yingozi, iphakamise kokubili ukukhathazeka kwezempilo kanye nezindleko zokulahla imvelo. Impilo ehlongozwayo yebhethri ye-Lithium-Ion cishe iminyaka emi-3 kusukela ekukhiqizweni.
I-Lead Acid ubuchwepheshe obufakazelwe futhi bungabiza kancane. Ngenxa yalokhu zisasetshenziswa eningini lezicelo zezimoto zikagesi nasekuqaliseni izicelo. Njengoba umthamo, isisindo, amazinga okushisa okusebenza kanye nokunciphisa i-CO2 yizici ezinkulu ezinhlelweni eziningi, amabhethri e-LiFePO4 asheshe abe yindinganiso yezimboni. Nakuba intengo yokuqala yokuthenga ye-LiFePO4 iphakeme kune-asidi yomthofu, impilo yomjikelezo omude ingayenza ibe yisinqumo esihle ngokwezezimali.

Ubuchwepheshe bebhethri ye-lithium busesebusha. Njengoba lobu buchwepheshe buthuthukile, ukuthuthukiswa okufana nezinhlelo zokuphatha ibhethri ezididiyelwe (i-BMS) kanye namakhemikhali angaphakathi azinzile kubangele amabhethri e-lithium aphephile kunabalingani bawo be-lead-acid futhi anikeze izinzuzo eziningi.
Ibhethri ye-Lithium ephephe kunazo zonke: i I-LiFePO4
Njengoba sishilo ekuqaleni, inketho ethandwa kakhulu yamabhethri e-lithium RV yibhethri ye-lithium iron phosphate (LiFePO4). Amabhethri e-LiFePO4 anomthamo wamandla ophansi kunamabhethri e-Li-ion, okuholela ekutheni azinze futhi awenze abe inketho enhle kakhulu yezinhlelo zokusebenza ze-RV.
Enye inzuzo yokuphepha ye-LiFePO4 ukuthi i-lithium iron phosphate ayinabo ubuthi. Ngakho-ke, ungayilahla kalula kunamabhethri e-lead-acid kanye ne-Li-ion.
Izinzuzo zamabhethri e-Lithium
Ukucatshangelwa kokuphepha kwamabhethri e-LiFePO4 ngokusobala kubalulekile. Kodwa-ke, ezinye izinzuzo eziningi zisiza ekwenzeni amabhethri e-LiFePO4 abe inketho efanelekile yekalishi legalofu, imoto kagesi(EV) , yonke imoto ye-terrain(ATV&UTV), imoto yokuzijabulisa(RV), isikuta sikagesi.
I-Longer Life Span
Abanye abantu bayakweqa intengo ephezulu kumabhethri e-lithium, angafinyelela kalula ku-$1,000 lilinye. Kodwa-ke, amabhethri e-lithium angahlala isikhathi esiphindwe kashumi kunebhethri elijwayelekile le-lead-acid elivame ukuphumela ekongeni kwezindleko ngokuhamba kwesikhathi.
Iphephe kune-Lead Acid noma i-AGM
Nakuba amabhethri amaningi e-lead-acid noma e-AGM evaliwe ukuze kuthuthukiswe ukuphepha kwawo, awakazinikezi izici zokuphepha eziningi ezenziwa amabhethri e-lithium.
Amabhethri e-lithium ngokuvamile anesistimu yokuphatha ibhethri edidiyelwe (i-BMS) ewasiza ukuthi ashaje futhi asebenze kahle kakhulu nangokuphepha. Amabhethri e-lead-acid nawo asengozini yokulimala kanye nokushisa ngokweqile lapho eshajwa futhi ekhishwa kodwa awanayo i-BMS yokuwavikela.
Ukwengeza, amabhethri e-LiFePO4 enziwe ngezinto ezingezona ezinobuthi ezimelana nokubaleka okushisayo. Lokhu kwenezela ekuvikelekeni okwengeziwe komsebenzisi kuphela kodwa nemvelo.
Amandla ebhethri amaningi
Enye inzuzo kumabhethri e-lithium ukuthi anamandla amakhulu asebenzisekayo uma kuqhathaniswa namabhethri e-lead-acid.
Ungakhipha ngokuphephile kuphela ibhethri le-asidi yomthofu ukuya cishe ku-50% wesilinganiso salo somthamo ngaphambi kokuba uqale ukulimaza ibhethri. Lokho kusho ukuthi uma ibhethri le-lead-asidi likalwe ngamahora ayi-100 amp-amp, unamahora angaba ngu-50 kuphela wamandla asebenzisekayo ngaphambi kokuthi uqale ukulimaza ibhethri. Lokhu kunciphisa umthamo wayo wesikhathi esizayo kanye neminyaka yokuphila.
Ngokuphambene, ungakhipha ibhethri ye-lithium cishe ngokuphelele ngaphandle kokudala umonakalo. Kodwa-ke, abantu abaningi abawasusi ngaphansi kuka-20% ngaphambi kokuwashaja. Ngisho noma ulandela lo mthetho wokugomela wesithupha, ibhethri ye-lithium engu-100 amp-hour inikeza cishe amahora angama-80 amp-amp ngaphambi kokuthi idinge ukushajwa.
Isondlo Esincane
Iziqaphi ezididiyelwe ze-BMS futhi zisiza ukugcina ibhethri lakho le-lithium, lisusa isidingo sokwenza lokhu ngokwakho.
I-BMS iqinisekisa ukuthi ibhethri ayishajiwe ngokweqile, ibala isimo sokushajwa kwamabhethri, iqaphe futhi ilawule izinga lokushisa, futhi iqapha impilo nokuphepha kwamabhethri.
Isisindo Esincane
Kunezindlela ezimbili amabhethri e-lithium anganciphisa ngazo isisindo sesistimu yebhethri lakho.
Njengoba sishilo ngaphambili, amabhethri e-lithium anamandla asebenziseka kakhulu kunamabhethri e-lead-acid. Lokhu kuzovame ukukuvumela ukuthi udinge amabhethri e-lithium ambalwa kusistimu yakho ukuze uzuze umthamo ofanayo nesistimu ye-lead-acid. Ukwengeza, ibhethri ye-lithium izoba nesisindo esicishe sibe uhhafu njengebhethri elinomthofu elinomthamo ofanayo.
Kusebenza Kakhulu
Njengoba sekushiwo, amabhethri e-lithium asebenza kahle kakhulu kunamabhethri e-lead-acid. Ngisho nesilinganiso somthamo ofanayo, amabhethri e-lithium anikeza amandla asebenziseka kakhulu. Aphinde akhiphe ngenani elizinzile kunamabhethri e-lead-asidi.
Lokhu kukuvumela ngempumelelo ukuthi usebenze isikhathi eside ngaphandle kokuthi uphinde ushaje amabhethri akho, okuwusizo ikakhulukazi uma u-boondocking futhi ikuvumela ukuthi unciphise ukusetshenziswa kwe-generator futhi wandise amandla akho elanga.
Okungabizi Kancane Kukonke
Nakuba amabhethri e-lithium ekuqaleni abiza ngaphezu kozakwabo be-lead-acid, iqiniso lokuthi ahlala isikhathi eside izikhathi ezingu-6-10 kusho ukuthi ekugcineni uzogcina imali ngokuhamba kwesikhathi.
I-JB BATTERY iyithimba lochwepheshe, elicebile elinolwazi, nethimba lezobuchwepheshe eliqinile labakhiqizi bebhethri ye-lifepo4, elihlanganisa iseli + ukuphathwa kwe-BMS + Ukwakheka kwesakhiwo sephakethe nokwenza ngokwezifiso. Sigxile ekuthuthukisweni nasekukhiqizeni ngokwezifiso amabhethri e-lithium iron phosphate.
